(o1. 220 -57) 1 An object of the invention is to'provide a cover of the character described having meansffor' placing the cover into or releasin'g it from locked and sealed engagement with the barrel, which in the operativeposition of the cover lies .concealed thereunder, but maybe'readily operated from the exterior thereof both for locking and releasing purposes while the coveris engaged in the opening. 7 A Another object of the inventionis to provide a cover of the character described inwhich no part thereof will protrude beyond the end of the barrel when the cover effects a full closure of the barrel. Q

a cover of the character described inwhich but a single displaceablepart'is exposed on the cover when the latter is in fully closed position over the barrel opening. 7 v I v A'still further object of the invention is to provide a cover of the character described in which the locking and releasing means,; while I carried on the under side of the cover, may be '30 in part temporarily moved to the exposed side of the cover. for facilitating. the actuation {of The invention tures' of advantage, some of which, with. the foregoing-will be set forthv in the following description of the preferred form of the invention which is illustrated in the drawings accompanying'and forming part of the specification; e It' is to be understood; however, that variations the showing made by the said vdrawings and de scription may be adopted .within. the scope 'of the invention as set forth ingthe'claims.

Asv illustrated in the drawings th'e; cover oi my invention is 7 arranged; for use with a type 'zo a of m'etalbarrel or drum Shaving one end wall 6,- preferably: --the top, formed -With a' marginal rolled head '7- which defines -.the,1;m' ainj opening- 810i the barrel. The cover, as clearly shown vin Figures 3 and 4, ,comprises a, closure ;plate 9" tofieat 1 11 t ea h st eq ve js'. oper-A atively disposed over the-barrelopening;V It

head 7 is annular; and in 'conformitytherewith the recessed portion 1-1 and. gasket 12 are similarly formed, Also the Wall 6 is spacedisufiiciently inward from-the end-of LthB baITGI so that the plate, including 'the portion '11, will; lie,.within the sides of the b'arrel :When th" cover oberatively disposed. over the openingn Means are-provided on the-coverjfor forcing and holdingthe same onto ,thexen'd wall;.when

the cover is operatively positione'dover'the' open- 1 '90 barrel with a -v sea-led ijoint lthe'reb'e'tweeni Posi tione'd'on the under: side,of'the plate. 'and'slida I blyacarriedlion guidesiili affixed to the plate" adjacent the outer edge thereof, are ;a "plurality of arms or bolts "15 which xare arra'nged;to be moved substantially radially of the; "cover". into or out 0f vengagement.with thefunder side-17 of 1 the wall 6. Movement of the ar'ms' islcontrolled by means of -an actuator-.member lil which; as here-shown is mounted forrotation'on a cylindrical'fiange*19 ,dependingacentrally from-the plate; Each of the 1armsis' pivotally connected at the inner end of them'em'berlS so that upon rotation of the latter the arms may beretra'cted a I to lie within the outer edges of themplate as shown in Figure 2', or :they imay be extended,

.toengage the 'e'ndywallfi 'as indicated'in Figure 1. It'will-be clear that when the 'armsare in theformer' position'the cover may be readily whereas when the arms are extended and en- 'sufiiciently to move the connecting point of the arms therewith to, a position. beyond. the line intersecting such point .andicthepoint at.

pressed against the head whereby a sealed joint maybe provided. Preferably in moving the actuator member to engage the end Wall, when;v

the arms are retracted, the .member isrotated which the arm is slidably connected 'to -the plate at its outer. end. In this manner with the engagement of the arms and. end wall such as toresiliently resist retraction of thearms, the latter will become automatically locked in extended position and retractable only upon reverse rotation ofthe actuator: Movement of actuator in both directions of rotation is preferably limited by engagement of the side edgesv of the 7 arms with the angularly related sides of the bearing members 14. V i

In order tofacilitate the ready engagementof the arms with the wall 6;the outer ends of such arms are beveled on their' upper sides. It is; to be, noted than; an extremely light and simple but-strongconstruction 'is 'provided by the de= sign ofthe parts as here shown. 'For instance the arms are formed of sheet metal bent to. channel form as-illustrated Figure- 5'.

Also

1 the actuator memberis -stamp'ed in one piece and pivotal attachment thereof 'to the'arrns-gis-i'fef fected: by rivets formed as a part of the member andisecured' tcfithe body portion of the arm channel. I

As the means "on the cover for *engaging or releaSing the wall 6;; is-located entirely-on the under side of the plate, the exposed side of the cover need have practically no moving" parts, nor

"parts protruding beyond the end= ofthe barrel".- In this: manner, even when the covers are oper ati'vely" heldon the barrels, the latter may-be piled end to end, as in shipping or forstorage,

in compact anduniform formation. It will be evident, however, that in view of the concealed positioning of said means, including theac'tua tor member, proper access should be had'to such actuator for effecting-the rotation thereof from theiexposed side of'the cover-when the latter is operatively disposed in'the opening. -I-n ac'corde ance therefore means areprovided for afiord ing such. access. Formed in the-plate at the central portion. thereof} and' in concentric relation to the-actuator, is'a hole 21'acr0s'sjthe botto1'n of which extends aportion '22" of the-actuator.

The hole 21 is threadedforengagement with'a I center of the. cover (plate with, itsilower'end en-j plug, 23 which may 'b'e screwed into" or out of the hole; tromthe exterior of the covere It will be clear that when the plug is removed access may be had to. the: actuator: so: that by applying a propertool thereto rotation thereof may be effected. ..M'ea-ns. are provided; however, whereby an associated part of the; actuator may be temporarily projectedfthrough'the hole 21- and above the cover soithat'rotation: of the. actuator may be accomplished by merely applyingia wrench or other; suitable ,tool to the top oflthe cover.

QM'ounted in the actuator for rotation therewith at, the center of turningthereof is. what may member and throughthehole 2.1.. 'Bymeans, of

stops 26: and'2'7 provided onthe member 24, the latter may assume the normal depressed position shown in Figure 3' or the elevated position shown in Figure 4. With the member 24in the. first mentioned position,- the plug 23 may; be operatively engagedin the hol'e "to seal thesame, but in orderfto allow thef'gripping member to be raised to its elevated" position the plug shouldbe removed.

The operation of the closure is as follows Assuming. thebarrel is to be closed, the cover', with the arms in retracted position, is primar:

ily set into the: barrelopening so'that the gasket restson the bead The plug if it is in the hole, is removed, and the gripping element raised to elevated position with the operators fingers or in; any other suitable-manner. Then with the element so positioned, a wrench or other. ap-

propriate tool is applied'thereto at the 'top of the cover and rotated to force the arms into engagement with the end 'plate. 7 When the arms have been sufficienly extended 'to" effect the seal between the cover and plate, the wrench or tool is removed from the gripping element whereby 'the'latter' will drop. toits depressed position and cover it is merely necessary"to removetheplug,

raise the gripping element and" then applythe tool or wrench thereto to retract T the arms.

/ InFig'ure'TI have shown a-jslightly modified 7 form of the'invent'ion. In this'embodimentthe gripping element 24 isomitted, the necessary rotation of the actuator. member being arranged to be effected b'y means of a toolsuch as the lever 31 which i's'insertable through the plate hole 21 froin the exterior of the cover and releasably engageable with said member to ro- 'vided in the-portion of the actuator visible through the-hole 21-. The advantage of the *t'ate' same. A simple form of releasable conarrangement of this embodiment overthe first described, is that the necessity of manipulating U the gripping element- 24 is 'despensed with,'.but

on the other hand a more 'or' less' special tool is required for effecting the rotationof th'ei ac bl 131701 member. 1 In the embodiment shown in. Figures} and 9,. the gripping element 41is1notonly unitarily included with the actuator, but is designed to extending. above the cover plate. v as here "shown is: mounted for rotation. at. the
